-A multiplatform Kotlin library providing basic IO primitives. `kotlinx-io` is based on [Okio](https://github.com/square/okio) but does not preserve backward compatibility with it. - -## Overview -**kotlinx-io** is built around `Buffer` - a mutable sequence of bytes. - -`Buffer` works like a queue, allowing to read data from its head or to write data to its tail. -`Buffer` provides functions to read and write data of different built-in types, and to copy data to or from other `Buffer`s. -Depending on the target platform, extension functions allowing data exchange with platform-specific types are also available. - -A `Buffer` consists of segments organized as a linked list: segments allow reducing memory allocations during the buffer's expansion and copy, -with the latter achieved by delegating or sharing the ownership over the underlying buffer's segments with other buffers. - -**kotlinx-io** provides interfaces representing data sources and destinations - `Source` and `Sink`, -and in addition to the *mutable* `Buffer` the library also provides an *immutable* sequence of bytes - `ByteString`. - -An experimental filesystem support is shipped under the `kotlinx.io.files` package, -which includes the `FileSystem` interface and its default implementation - `SystemFileSystem`. - -`FileSystem` provides basic operations for working with files and directories, which are represented by yet another class under the same package - `Path`. - -There are two `kotlinx-io` modules: -- [kotlinx-io-bytestring](./bytestring) - provides `ByteString`. -- [kotlinx-io-core](./core) - provides IO primitives (`Buffer`, `Source`, `Sink`), filesystems support, depends on `kotlinx-io-bytestring`. - -## Using in your projects - -> Note that the library is experimental, and the API is subject to change. - -### Gradle - -Make sure that you have `mavenCentral()` in the list of repositories: -```kotlin -repositories { - mavenCentral() -} -``` - -Add the library to dependencies: -```kotlin -dependencies { - implementation("org.jetbrains.kotlinx:kotlinx-io-core:0.5.4") -} -``` - -In multiplatform projects, add a dependency to the `commonMain` source set dependencies: -```kotlin -kotlin { - sourceSets { - commonMain { - dependencies { - implementation("org.jetbrains.kotlinx:kotlinx-io-core:0.5.4") - } - } - } -} -``` - -### Maven - -Add the library to dependencies: -```xml - - org.jetbrains.kotlinx - kotlinx-io-core-jvm - 0.5.4 - -``` - -### Android - -`kotlinx-io` is not tested on Android on a regular basis, -but the library is compatible with Android 5.0+ (API level 21+). - -## Contributing - -Read the [Contributing Guidelines](CONTRIBUTING.md). -

More information -about different sizes of characters can be found here: - https://en.wikipedia.org/wiki/UTF-8 - -Encoding was pretty easy, but decoding is a bit more complicated. We need to -first determine the number of bytes used to represent the character, strip all -the headers, and then combine all the bits into a single integer. Let's use the -character we just encoded and work backwards, taking advantage of 2's complement -integer representation and the XOR function. - -Let's look at the decimal representation of these bytes: - - 0xe2, 0x88, 0x87 = -30, -120, -121 - -The first interesting thing to notice is that UTF-8 headers all start with 1 - -except for ASCII which is encoded as a single byte - which means all UTF-8 bytes -will be negative. So converting these to integers results in a lot of 1's added -because they are store as 2's complement: - - 0xe2 = -30 = 0xffff ffe2 - 0x88 = -120 = 0xffff ff88 - 0x87 = -121 = 0xffff ff87 - -Now let's XOR these with their corresponding UTF-8 byte headers to see what -happens: - - 0xffff ffe2 xor 0xffff ffe0 = 0x0000 0002 - 0xffff ff88 xor 0xffff ff80 = 0x0000 0008 - 0xffff ff87 xor 0xffff ff80 = 0x0000 0007 - -***This is why we must first convert the byte header mask to a byte and then -back to an integer, so it is properly converted to a 2's complement negative -number which can be applied to each byte.*** - -Now let's look at the binary representation to see how we can combine these to -create the Unicode code point: - - 0b0000 0010 0b0000 1000 0b0000 0111 - 0b1110 xxxx 0b10yy yyyy 0b10zz zzzz - -Combining each section will require some bit shifting, but then they can just -be OR'd together.
